Press release date: April 2, 2014

A new bolt seat resurfacing tool that makes sure turbine cover bolts fit properly after repairs, and is suitable for all surfaces subjected to corrosion is being introduced by ESCO Tool of Holliston, Massachusetts.

The ESCO MILLHOG® BSR Tool features a cutting head that is equipped with three flat-face blades to cleanly remove corrosion and resurface turbine shell diaphragm retainer bolt holes. Capable of 0.001” flatness accuracy, this tool can remove metal up to 1.5” deep and be equipped with different sized heads to fit the hole and circumference that requires resurfacing.

Fully portable to provide a fast and accurate way to resurface multiple retainer bolt holes without cutting fluids, the ESCO MILLHOG® BSR Tool uses TiN coated blades in a secure blade lock system and has a robust gear drive that is field-proven in numerous beveling and pipe machining applications. It is offered in pneumatic, electric, and battery powered configurations.

The ESCO MILLHOG® BSR Tool is priced from $4,995.00 and is offered in a wide range of sizes. Pricing is available upon request.
